These are games that I have copied from Wii memory to SD and I wondered if anyone had written a small app that reads the folder names and show exactly what games are on there instead of manually working it out (or sticking it in the Wii)

If you own the games, the code will be on the back of the box above the barcode. If you don't the barcode should be in the ISO somewhere if you can be arsed to extract them and search them.
Not to forget if you move each save over one by one (which would be incredibly slow), you'll know which ones they are.

I download a VC or WiiWare game into the Wii memory, then I copy them to the SD using the Wii and delete them from my Wii memory until I want to play them again. they are transferred over by the Wii into a predetermined folder structure.

I should explain why I want to view on PC, I have 30+ games stored on my SD card and already it is a pain reading through them by using the tooltip to see what they are.

if there were a way of checking the card on a PC and creating a list of games (maybe printed out with icon and title) I could keep better track of what I have, it is bad enought now and as soon as I get my 4gig (non sdhc) card and start loading it up I will lose the will to live.

A Wii util that dumped the game_id and game_name to a text file would be good enough for me to edit into any format I wanted on my PC, especially if it could do this in batch for all the games stored on SD.
